Trucking demand visibility is far more important than supply

The point is that capacity shifts are slow and stable, while demand changes much more rapidly and is very unpredictable over time. This is the consummate struggle of supply chains and transportation companies across the globe — how much infrastructure (capacity) is needed to be able to flex up but not have too much overhead when demand softens?

The process of ordering and seating a truck takes close to a year. That truck can haul roughly seven 500-mile loads per week, or 360 loads per year. This only occurs if shipping patterns are consistent and drivers are readily available, and neither are true. 

So it isn’t a pure question of how much capacity is available in aggregate, but are those trucks available in the right places at the right times in general? This metric is extremely difficult to attain.

Since demand is uneven and spread unevenly throughout the country, trucks and drivers need to exceed the number of shipments available. So even if capacity grows by 1%, it just increases the chances that loads will be covered marginally.

If you ship it they will come

Demand determines supply in transportation. Trucking companies position their fleets and facilities where there is consistent need for their services. For this reason, knowing where and when demand is changing is critical as it will determine the growth or decline in transportation availability. 

Over the past year, total trucking demand has declined roughly 29% at a minimum. But that rate of decline has been extremely varied across the U.S. Texas demand has shrunk roughly 20% over the past year, while California OTVI has dropped around 40%. 

Looking at outbound tender market share values, which measure market demand in relation to each of the 135 markets in the U.S., Southern California volumes are down significantly when compared to Houston and Detroit. Houston is over 1,500 miles away from Los Angeles and it is very difficult to reposition trucks and drivers this quickly.  

Changes in relative demand matter just as much if not more than aggregate demand in regard to transportation. 

We already have the answer we need

Probably more important than any of the previous points is that there are already measures of  the relationship between supply and demand in trucking. Tender rejection rates (OTRI) and spot rates (NTI) measure when capacity is meeting demand in the contract and spot markets, respectively.  

There is little use for knowing how much capacity is available in the for-hire freight market other than being interesting. But there is exceptional value in knowing how well capacity and demand are lining up and in what direction they are trending. 

Since December 2021 tender rejection rates have fallen from over 20% to under 4%, while spot rates are down 27%. 

Demand-side indicators are probably the most crucial to getting the earliest signs of market shifts, while rejection rates and spot rates answer the two most important questions that companies want answered: Can I get a truck and how much will it cost me?
